Claims

[Scope of utility model registration request]

A frame forming the main body, a platen around which recording paper is wound, and a carriage movable along the platen.
A thermal head is mounted on this carriage and arranged to face the platen, a tape cassette is arranged on the carriage and stores a position tape for monitoring the heat-melting material, and A thermal printer that is equipped with a tape winding mechanism that winds up a printing tape, places the printing tape between a recording paper wound around a platen and a thermal head, and prints on the recording paper by pressing the thermal head against the platen. a shaft that extends along the platen and is rotatable; a head pressure release mechanism that presses the thermal head against the platen and releases the pressure contact in conjunction with the rotation of the shaft; and the shaft. a tape winding stop mechanism that stops the winding operation of the printing tape in conjunction with the rotation of the shaft; and a cassette shift mechanism that disposes the tape cassette at a plurality of height positions in conjunction with the rotation of the shaft. The head pressure release mechanism includes a head holding means that holds and is rotatable for the thermal head, and a pressure contact that engages with the head holding means and is rotatable in accordance with the rotational movement of the shaft. 1. A thermal printer comprising: a cam, the head holding means being rotated in accordance with the rotation of the pressure contact cam.
